Ponena zazida zomvera, amplifier imagwira ntchito yofunika kwambiri podziwa mtundu wonse wa mawu a dongosololi. Pakati pa zinthu zambiri zomwefotokozani momwe amplifier imagwirira ntchito, kuchuluka kwa mayankho afupipafupi ndi chimodzi mwazofunikira kwambiri. Kumvetsetsa momwe kuchuluka kwa mayankho afupipafupi kumakhudziramtundu wa mawuzingathandize anthu okonda kumva ndi omvera onse kupanga zisankho zolondola posankha zida zomvera.

Kodi kuyankha pafupipafupi n'chiyani?

Kuyankha pafupipafupi kumatanthauza kuchuluka kwa ma frequency omwe amplifier imatha kubereka bwino. Nthawi zambiri imayesedwa mu Hertz (Hz) ndipo imawonetsedwa ngati mtunda, monga 20 Hz mpaka 20 kHz. Mtundu uwu umaphimba kuchuluka kwa ma frequency omwe amamveka kwa anthu ndipo nthawi zambiri amaonedwa kuti ndi kuyambira 20 Hz (bass yotsika kwambiri) mpaka 20 kHz (treble yapamwamba kwambiri). Amplifier yokhala ndi ma frequency response range ambiri imatha kupanga ma spectrum ambiri, zomwe zimapangitsa kuti kumvetsera kukhale kosangalatsa kwambiri.

Kufunika kwa Mayankho Obwerezabwereza

1. Kubereka kwa Bass: Malekezero otsika a frequency spectrum, omwe nthawi zambiri amakhala pansi pa 100 Hz, ndi komwe kumakhala ma bass frequency. Amplifier yomwe imatha kubwereza molondola ma frequency otsika awa imabweretsa kuchulukirachulukira komanso kochulukirapo.chidziwitso chomveka bwino.Kwa mitundu yomwe ikufunikabass yozama, monga nyimbo zamagetsi, hip-hop, ndi nyimbo zakale, amplifier yokhala ndi ma frequency response omwe amafika pa 20 Hz ingathandize kwambiri kuti mawu akhale abwino.

2. Kumveka Bwino kwa Pakati: Ma frequency apakati (pafupifupi 300 Hz mpaka 3 kHz) ndi ofunikira kwambiri pa kumveka bwino kwa mawu ndi ma tymbre achilengedwe a zida. Amplifier yomwe imachita bwino kwambiri pamtunduwu imatsimikizira kuti mawu ndi zida zimamveka bwino.zomveka bwinondipo ngati zenizeni. Ngati mayankho a pafupipafupi ali ochepa pamlingo uwu, phokoso lidzakhala losamveka bwino komanso losamveka bwino, zomwe zimakhudza momwe munthu amamvera.

3. Tsatanetsatane wa Treble: Ma frequency apamwamba, makamaka omwe ali pamwamba pa 3 kHz, amathandizira kuti mawu amveke bwino komanso momveka bwino. Zida monga ma cymbals, zitoliro, ndi ma violin zimapanga mawu ofanana ndi awa. Amplifier yomwe imatha kubwereza ma frequency amenewa molondola ingapereke malo ndi tsatanetsatane, ndikukweza mtundu wonse wa mawu. Kuyankha kosakwanira kwa ma frequency mu treble kungayambitse kufooka kapena kufooka.mawu opanda moyo.

Momwe mayankho afupipafupi amakhudzira mtundu wa mawu

Kuyankha kwa ma frequency a amplifier kumakhudza mwachindunji momwe imapangira mitundu yosiyanasiyana yazizindikiro za mawu.Nazi njira zazikulu zomwe ma frequency response amakhudzira mtundu wa mawu:

1. Kupotoza ndi Kukongoletsa Maonekedwe: Ngati amplifier singathe kubwerezanso ma frequency enaake, ikhoza kuyambitsa kupotoza kapena mtundu wa mawu. Mwachitsanzo, ngati amplifier singathe kugwira bwino ma frequency otsika, ikhoza kupanga bass yopotoka yomwe siili bwino. Kupotoza kumeneku kumawonekera makamaka m'malo ovuta kumene zida zambiri zimayimba nthawi imodzi.

2. Mphamvu Yosinthasintha: Anmtundu wa mphamvu wa amplifierlimatanthauza kusiyana pakati pa ma voliyumu opanda phokoso kwambiri ndi okwera kwambiri omwe amatha kubereka. Mayankho ambiri a pafupipafupi nthawi zambiri amatanthauza ma dynamic range akuluakulu, omwe amalola amplifier kuthana ndi zovuta zazing'ono komanso ma crescendo amphamvu popanda kusokoneza. Luso limeneli ndilofunikira kwambiri pamitundu yomwe imadalira dynamic contrast, monga nyimbo zakale ndi jazz.

3. Kuyankha kwa Gawo: Kuyankha kwa pafupipafupi sikungotanthauza kuchuluka kwa phokoso pamafupikidwe osiyanasiyana, komanso kumakhudzanso kuyankha kwa gawo, komwe ndi nthawi yamafunde a phokoso. Ma amplifier omwe ali ndi gawo loipa angayambitse mavuto a nthawi, zomwe zimapangitsa kuti phokoso lisagwirizane kapena lisagwirizane. Izi zimawononga kwambiri makina a stereo, komwe kujambula molondola ndi malo omveka bwino ndizofunikira kwambiri pakumvetsera mozama.

4. Kugwirizana ndi okamba nkhani: Mayankho a pafupipafupi a amplifier ayeneranso kugwirizana ndi ma speaker omwe amayendetsa. Ngati amplifier ili ndi mayankho ochepa a pafupipafupi, singagwiritse ntchito mokwanira magwiridwe antchito a speaker yapamwamba. Mosiyana ndi zimenezi, amplifier yapamwamba kwambiri yokhala ndi mayankho ambiri a pafupipafupi ingagwiritse ntchito mokwanira magwiridwe antchito a speaker mpaka momwe ingathere.

Kusankha Chokulitsa Choyenera

Litikusankha amplifier, ndikofunikira kuganizira kuchuluka kwa mayankho a pafupipafupi pamodzi ndi zina monga kusokonezeka kwa harmonic (THD), chiŵerengero cha signal-to-noise (SNR), ndi mphamvu yotulutsa. Amplifier yogwira ntchito bwino simangokhala ndi mayankho ambiri a pafupipafupi komanso kusokonezeka kochepa komansomphamvu yotulutsa kwambirikuti azitha kuyendetsa bwino ma speaker.

Kwa anthu okonda kumvetsera, akulimbikitsidwa kumvetsera ma amplifiers osiyanasiyana pamalo olamulidwa kuti awone momwe mawu awo alili. Samalani momwe amplifier imapangira bwino ma bass, ma frequency apakati, ndi ma treble. Amplifier yabwino iyenera kupereka mawu oyenera pa ma frequency onse, zomwe zimapangitsa kuti munthu azimvetsera bwino.

Pomaliza

Mwachidule, kuchuluka kwa mayankho a pafupipafupi a amplifier ndi chinthu chofunikira chomwe chimakhudza kwambiri mtundu wa mawu. Kuyankha pafupipafupi kwambiri kumalola kuti mawu a bass apangidwe bwino, kumveka bwino pakati, komanso tsatanetsatane wa treble, zonse zomwe zimapangitsa kuti kumvetsera kumveke bwino komanso kosangalatsa. Pomvetsetsa kufunika kwa mayankho a pafupipafupi, ogula amatha kupanga zisankho zolondola posankha ma amplifier, kuonetsetsa kuti akupeza mtundu wabwino kwambiri wa mawu kuchokera ku makina awo amawu. Kaya ndinu womvera wamba kapena wokonda kwambiri mawu, kulabadira mayankho a pafupipafupi kungakupangitseni kumva bwino mawu anu.
